Question

Radius of a circle is 3.5 centimetre find the circumference and area of the circle

Answer 1

Given that,

Radius of a circle is 3.5 centimetre

To find the circumference and area of the circle​.

Step-by-step explanation:

We know that,

Circumference of a circle is,

`2\pi r`

where r is the radius of the circle.

Here, r=3.5

Substitute the value of r, we get

`=2*\pi*3.5`

Substitute the value of pi=22/7, we get

`=2*(22)/(7)*3.5`
